"There is no limit to the number of times you can visit Canada in one year. However, if you plan to stay for longer than six months at a time, you will need to apply for a Temporary Resident Visa. Otherwise, simply present your valid passport at the border, and you will be granted entry. Remember that days spent in transit (in transit means passing through Canada en route to another country) do not count towards the 180-day limit.
Even if you are feeling well when you leave Canada, illness might become apparent during your flight or shortly after that. For this reason, we strongly recommend purchasing travel insurance that includes emergency medical coverage and repatriation before your trip."
